UCC2941-3 - Unitrode

UCC2941-3 (UCCx941-x) 1V Synchronous Boost Converter

The UCC3941 family of low input voltage single inductor boost converters are optimized to operate from a single or dual alkaline cell, and step up to a 3.3V, 5V, or an adjustable output at 500mW. The UCC3941 family also provides an auxiliary 9V 100mW output, primarily for the gate drive supply, which can be used for applications requiring an auxiliary output.

Features

• 1V Input Voltage Operation Startup Guaranteed Under Full Load on Main Output With Operation Down to 0.4V
• Input Voltage Range of 1V to VOUT + 0.5V
• 500mW Output Power at Battery Voltages as Low as 0.8V
• Secondary 9V Supply From a Single Inductor
